Frequently Asked Questions

How do I start a new game?
Tap the “Challenges”/"Start" button on the main menu. Start at first difficulty level and challenge the AI.
Why can’t I place a unit on a cell?
• Make sure the unit you are dragging has remaining uses (number badge > 0).
• You can only place a stronger unit on top of a weaker one.
• In Tutorial mode, follow the on-screen guidance bubble.
How do I reset my progress?
On the main menu, tap “Reset” to clear all scores and settings. This cannot be undone.
The AI seems stuck or not responding—what do I do?
• Check your internet or device performance—although our AI runs locally, device lag can sometimes affect animations.
• Restart the app. If the issue persists, contact support below.
